Domain and Range Precalculus

Front

What is the domain in inequality/algebraic notation?

Back

The domain is the set of all possible input values (x) for a function, expressed in inequality notation.

Front

What is the range in inequality/algebraic notation?

Back

The range is the set of all possible output values (y) for a function, expressed in inequality notation.

Front

What is the range in interval notation?

Back

The range can be expressed in interval notation, which shows the set of output values as intervals.

Front

What is the domain in interval notation?

Back

The domain can be expressed in interval notation, which shows the set of input values as intervals.

Front

When identifying domain and range, what symbol(s) is used when the value is not included?

Back

Parentheses ( ) are used to indicate that the endpoint values are not included in the interval.

Front

What does the notation [a, b] represent?

Back

It represents a closed interval where both endpoints a and b are included in the domain or range.

Front

What does the notation (a, b) represent?

Back

It represents an open interval where neither endpoint a nor b is included in the domain or range.

Front

How do you find the domain of a function?

Back

To find the domain, identify all x-values that can be input into the function without causing any undefined situations.

Front

How do you find the range of a function?

Back

To find the range, determine all possible y-values that the function can output based on the domain.

Front

What is the difference between domain and range?

Back

Domain refers to the set of input values (x), while range refers to the set of output values (y) of a function.
